HG Sheets - Super Desiccants

Humidity & Oxygen Getters

The lifetime and performance of encapsulated devices, such as OLED displays and lighting, OPV’s (organic photovoltaics), organic and printed electronics are limited by their sensitivity to moisture and oxygen.  Dynic’s HG Sheets, available in a multitude of formulations to meet your specific application needs, protect your device from corrosion, degraded performance, and early failure without requiring bake-out (drying) or activation time that slows down your production process.  

You can find a quick overview of our HG Sheet products in our HG Sheet QuickReference Guide.

HD Type

Moisture getter for OLEDs & OPVs

HGSheetReels.jpg

Fast absorption of moisture in OLED's and OPV's

Moisture is often outgassed by the polymeric materials inside hermetically sealed packages like OLED's and OPV's.  Using our humidity getters gives you the best long-term reliability assurance and extends the life of your device.

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 135-300microns
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation

HD-S Type

Moisture & oxygen getter for OLEDs, OPVs, & Electronic Devices

Fast absorption of both moisture & oxygen in OLED's, OPV's, and Electronic Devices

Seal leakage, the sealing process itself, and outgassing from adhesives and materials used in electronic devices, can all cause contaminants inside your device that can lead to degeneration or early failure  Using our humidity getters gives you the best long-term realiability assurance and extends the life of your device.

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 135-300microns
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation
 

SF Type

Low expansion moisture getter

High Performance Type

Same great moisture absorption but in a thinner, low expansion sheet

As our electronic devices continue to get smaller, the space inside the electronic packaging is at a premium, but the need to absorb moisture does not decrease.  That's where our high performance SF type HG Sheet comes in. 

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 100-250 microns
  • Available in both reel and sheet form to accommodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation
 

SG Type

Most highly absorbent moisture getter

HG-SHEETReelPkg

High Performance Type 

This moisture getter is thinner than the SF type and maintains high moisture absorption.                                             The SG type is suitable for for use in electronic devices that are more extremely sensitive to moisture.        Developed to accomodate further miniaturization and thinning of electronic devices..

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 100-170 microns  
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation
 

LD Type

Slow-acting moisture getter

20230420_151745

Slow-acting CaO type with low initial moisture absorption rate                                                                                  

Fast-acting moisture getter that reacts with moisture under atmospheric conditions requiring a dry box.  It can be handled under atmospheric conditions without a dry box and can be used for applications other than OLED devices.

  • Various form factors (thickness, sizes, and shapes) available. 
    • Total thicknesses ranging from 135-460 microns
  • Available in both reel and sheet form to accommodate your production process
  • No activation required

  • Peel-and-stick application allows for easy installation
